Title: Pickup arm on refuse collecting vehicle - has vacuum suction cups for gripping and lifting dust bin
Inventor: EDELHOFF GUSTAV
IPC: B65F3/02
Filed: 1975-12-23
Abstract: A pickup arm which is attached to a refuse collecting vehicle is carried by a horizontal shaft (2). A vertical lift frame (8) is located by two pairs of driven friction rollers (9) so that the frame (8) can be raised and lowered as is required. Centrally hinged fork levers are carried by horizontal cylinders (7) which are attached to the lifting frame. When a dust bin (21) is picked up, the elastic suction cups (6) at the free end of the fork levers are pressed against the smooth outside wall of the bin. A vacuum is then applied to the suction cups so that the bin can be raised and tilted into the collecting vehicle.

Title: Synthetic fibre solvent removal - using the storage can as a washing vessel with water carrying out solvent for recovery
IPC: D01D11/00
Filed: 1976-02-20
Abstract: A process for the removal of solvent from synthetic fibres after they have been spun into filaments and passed through a bath of dissolved polymer. As the spun fibres are gathered together from the various spinning stations, and laid in strands in cans before drawing, the solvent (e.g. OMF or HN03 for polyacrylonitrile fibres) is released in the holding cans. The process ensures that the fibre material is held at a constant character and quality, that solvent does not evaporate and lead to pollution and evade recovery for future use.

Title: Parallel channel signal transmission system - enables disturbances to be detected by comparison of signal with its inverse
Inventor: CERNY JOSEF DR ING
IPC: H04B1/74
Filed: 1976-05-10
Abstract: Detection of disturbances in signal processing systems is accomplished by transmission through two parallel channels. One channel carries the signal and the other the inverse of the signal comparator stages are used to detect the disturbance and to control output gating circuitry. The main transmission channel consists of a transmitter, amplifier, band filter, differentiator, trigger stage and output stage. A parallel channel has identical components, with the exception of the output stage comparators monitor the signal inputs to each stage and the coupled output controls a gate. When there is no disturbance the comparator stage output is a constant. Any disturbance manifest itself equally on both channels at the same point and the comparator output reacts accordingly.

Title: Opener for portable dosimeter casing - comprises pair of tongs with split ring to close onto casing or lid
Inventor: HOEGL ALOIS DIPL ING DR
IPC: G01T1/02
Filed: 1977-01-28
Abstract: An opening tool for a plate-type radioactive dosimeter is intended for reducing the dia. of the plastic casing or lid, so that the beading around the periphery of the one component becomes disengaged from the corresponding groove around the periphery of the opposite component and the two parts can thus be sepd. The tool comprises a pair of arms forming a tongs connected at pivot joint. A split ring of rectangular cross-section has its open ends fixed to the arms of the tongs near to the pivot joint, so that when the tongs are squeezed to close them, the ring is closed and its radius is reduced. The inner face of the ring is chamfered to give it a large internal radius of curvature at the side nearest the tongs than at the opposite side. The cross-section of the ring also decreases from its central portion to the ends adjacent to the split. Used for opening the plastic casing of a portable (worn) dosimeter contg. a plate-type sensitive element. By simply fitting the ring around the appropriate part, i.e. casing or lid, and squeezing the tongues, the joint can be opened and the plate-shaped element removed.

Title: Anti-burst vehicle glove box catch - has metal eye on pivoted arm free to rotate after failure of breakable mounting
Inventor: KRUEGENER ROLF DIPL ING
IPC: E05B83/30
Filed: 1977-06-11
Abstract: The locking mechanism for a motor vehicle glove compartment lid consists of a spring loaded latch (5, 6, 7, 8) mounted on the lid (1) and operated by a lever (7). The latch acts with a metal eye (9) fixed to the glove compartment structure (12) with a pivot (11) and a breakable plastics component (13) of double-T cross section. In a collision, if the roof (12) of the glove compartment rises relative to the hinge (3), the plastics component (13) breaks, and the arm (10) pivots downwards preventing disengagement of the catch. The glove compartment is covered externally with impact absorbing padding (14).

Title: Solenoid operated shutter linkage for camera - operates with return spring force uncoupled when shutter system is reset
Inventor: TANAKA HARUMI
IPC: G03B9/62
Filed: 1977-06-15
Abstract: The solenoid operated shutter linkage has a permanent magnet (4) which is partially opposed by the solenoid, to release a spring loaded linkage to operate the shutter. To reset the shutter the return spring force has to be overcome, and this is possibly by uncoupling the return force and allowing a relatively simple solenoid action to bring the shutter back to the permanent manget. The system eliminates shutter bounce and camera vibration. It provides a simple mechanism with just one solenoid.

Title: Power supply connected into HV DC distributor line - uses motor-generator set and static inverters to give AC output
Inventor: BOWLES JOHN P
IPC: H02J3/18
Filed: 1977-06-28
Abstract: The power supply can be connected by plug/socket connectors in series with an HV DC power distribution line. The line is broken by appropriately placed circuit breakers. An AC output is produced to drive local equipment. The effective power of the supply is derived from two static converters that can be switched into the HV line and whose outputs are coupled to an output transformer. The reactive power is derived from a motor/generator set whose motor is in series with the HV line. This set also triggers the thyristors in the converters and its output is likewise coupled to the output transformer.
